Washed Rind cheeses are cheeses that - you guessed it - get washed on the rind during production. Typically, they have a sticky, orange rind with an almost stinky feet kind of aroma. Generally they smell much worse and pungent than they taste! The most well known washed rind cheeses to the "average Ontarian" would probably be Oka or Raclette, but worldwide cheeses such as Epoisses, Vacherin Mont d'Or, Taleggio and technically even Gruyere are very popular and well known!
Washed Rind cheeses can have flavour notes of straw/hay, fruitiness, meat/bacon, or yeast/biscuit. They range in intensity, but those who love washed rind cheeses usually say the funkier the better! You can easily identify them by their rusty orange rind and can loosely predict their flavour profile.
When making these cheeses, cheesemakers will either dunk or brush the rind with some sort of brine - it could be wine must, saline, beer, brandy, spices - basically anything that would promote the growth of a bacteria called Brevibacterium Linens (aka B. Linens) which is where that sticky rind comes from! This process requires regular "washings", making it very labour-intensive compared to other methods of aging cheeses, which also gives a more artisanal and unique profile to each cheese!
The flavour profiles of washed rind cheeses is very hard to describe if you've never had one before, but if you want to get more into cheeses or learn more about what your favourite flavours are, it's definitely worth giving these a try! Start with something milder, such as Taleggio, Oka or Raclette and if the funk isn't off putting, step it up a little bit!
